The cops did a good job, that I will agree.
The good thing is if they are old style local police they will know if they get a call again they will remember their encounter with the family and respond accordingly.
We had a case here where a 10 year old (or thereabouts) boy rode his bike to the library less than half of a mile away. On the sidewalk. In daylight. Dressed for the weather. And still somebody called the cops. Because the boy rode his bike across a somewhat busy street to go to the park after he had been to the library. He crossed where he was supposed to. But by himself!!!!! To the park!!! Oh the horrors.
